Re: Importing wxWidgets Help

Thank you Tim for those comments. I've edited my code accordingly. Thank 
you.

Sorry about that -900. I forgot to remove the minus sign before I attached 
the zip file. I'm using a second monitor and that -900 positions the window 
fairly well on my second monitor. Just 900 positions it on my primary 
monitor which is the screen to my laptop. My second monitor is a large LCD 
screen, much easier for me to see.
